Question

The perimeter of a square is 48 cm the area of rectangle is 4cm less than the area of the square of length of the rectangle is 14 cm then find its perimeter
​

Answer 1

Answer:

Step-by-step explanation:

1. 48/4= 12 to get the length of square

2. 12*12=144 to get the area of square

3. 144-4 = 140 to get the area of rectangle

4.140/14 = 10 to get the perimeter

Answer 2

The perimeter of rectangle is 48 cm

Step-by-step explanation:

The perimeter of a square is 48 cm

Let side of square be s

$4s=48$

$s=12\ cm$

Let breadth of rectangle be b

Length, l = 14 cm

Area of rectangle, $A_R=14b$

Area of square, $A_S=12^2=144$

The area of rectangle is 4 cm² less than the area of the square.

$A_R+4=A_S$

$14b+4=144$

$14b=140$

$b=10\ cm$

Perimeter of rectangle = 2(l+b)

                                     = 2(14+10)

                                     = 48 cm
